The City of God is one of the most important works of Christian history and philosophy ever written. The writings of St. Augustine are as intriguing to the casual reader as it is to Christian researchers. St. Augustine's work provides insight into Western thought and the development of Western civilizations. The City of God provides the reader with an artful contrast between earthy cities and those in heaven as a representation of the eternal struggle between good and evil. The City of God was originally penned in the early 5th century as a response to the prevalent belief that Christianity was to blame for the fall of Rome. St. Augustine is known as one of the most influential Fathers of the Catholic Church. Born November 13, 354, Augustine would eventually be recognized as a Saint by the Catholic Church, the Eastern Christian Church, and the Anglican Communion.

This book was written in Latin by Augustine of Hippo (354 - 430) to discuss the Trinity in relation to God the Word (logos). Even though it is not as well known as some of his other writings, it is considered by many to be his masterpiece and of more doctrinal importance than either the Confessions or the City of God. St. Augustine is considered a saint in the Catholic Churches, the Eastern Orthodox Church, and the Anglican Communion. He is ranked among the doctors of the Church in the Roman Catholic Church.

In this famous treatise, St. Augustine (AD 354 - 430) covers the question of the role of free will in our lives and how it contrasts with the role of God's grace. He gives scriptural arguments to show that we cannot earn the grace of God, yet this does not deny the role that free will plays in our own salvation.

Written after the capture of Rome in 410 by Alaric, King of the Visigoths, St Augustine's City of God was intended as a response to pagan critics who blamed Christianity for this brutal defeat. Augustine attacks ancient pagan beliefs and relates the corruption and immorality that led to Rome's downfall, which began before Christ, before reaching his main argument: that the City of Man is perishing and only the Heavenly City of God will endure.

The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

Nothing except the Resurrection of Jesus Christ is a greater miracle or wonder in human history. God becoming flesh in human history is the greatest marvel. Jesus of Nazareth was foretold in the Torah and the Prophets centuries before his appearance, and he was proved to be real and not a pretender due to his death and Resurrection. The early church grappled with all of this intellectually.

Since the landmark Obergefell v. Hodges Supreme Court decision in 2015, sexual identity has dominated both public discourse and cultural trends — yet no historical phenomenon is its own cause. From Augustine to Marx, various views and perspectives have contributed to the modern understanding of the self.

Rev. Dr. Stephen De Young, creator of the popular The Whole Counsel of God blog and podcast, traces the lineage of Orthodox Christianity back to the faith and witness of the apostles, which was rooted in a first-century Jewish worldview. The Religion of the Apostles presents the Orthodox Christian Church of today as a continuation of the religious life of the apostles, which in turn was a continuation of the life of the people of God since the beginning of creation.

In this classic book, John of Damascus laboured to form one complete, clear, and brief theological work that would summarize all Christian doctrine that had been passed down and agreed upon. The following was said of the book: The result was an inexhaustible storehouse of tradition in which nothing is to be found that has not been either approved by the ecumenical synods or by the established leaders of the Church.

In his own day the dominant personality of the Western Church, Augustine of Hippo today stands as perhaps the greatest thinker of Christian antiquity, and his Confessions is one of the great works of Western literature. Now modern listeners will have easier access to St. Augustine's deeply personal meditations. Chadwick's lucid translation and helpful introduction clear the way for a new experience of this classic.

The Enchiridion, or as it is sometimes titled, Faith, Hope, and Love, is a short treatise on Christian piety, written in response to a request soon after the death of St. Jerome in 420. The essay was meant to serve as a model for Christian instruction (catechesis).

Catherine of Siena (March 25, 1347-April 29, 1380) was a mystic, activist, and author who had a great influence on Italian literature and the Catholic Church. Catherine's mystical theology was employed towards practical ends for her own spiritual life and those of others. She used the language of medieval scholastic philosophy in the Dialogue, a poetic and prophetic work. Advocating for continuous, humble prayer, she hears God the Father answering her requests in order to receive help to be saved. Catherine gives special importance to mental prayer, but also recommends vocal prayer.

Institutes of the Christian Religion is John Calvin's seminal work on Protestant systematic theology. Highly influential in the Western world and still widely read by theological students today, it was published in Latin in 1536 and in his native French in 1541. The book serves as an introductory textbook on the Protestant faith for those with some previous knowledge of theology and covers a broad range of theological topics from the doctrines of church and sacraments to justification by faith alone and Christian liberty.

A comprehensive explanation of Martin Luther’s most crucial and controversial beliefs on salvation, The Bondage of the Will is a critical resource in understanding the theology of free will and the gift of faith. Facing criticism even from others who had disagreements with the Catholic church, Luther’s strong and absolute beliefs on the gift of salvation were truly revolutionary. This work contains the full amount of research, discussion, and debate on Luther’s ideas on free will as it pertains to individual Christians and to their understanding of God.

Of all things Catholic, there is nothing that is so familiar as the Mass. With its unchanging prayers, the Mass fits Catholics like their favorite clothes. Yet most Catholics sitting in the pews on Sundays fail to see the powerful supernatural drama that enfolds them. Pope John Paul II described the Mass as "Heaven on Earth," explaining that what "we celebrate on Earth is a mysterious participation in the heavenly liturgy."

Nothing except the Resurrection of Jesus Christ is a greater miracle or wonder in human history. God becoming flesh in human history is the greatest marvel. Jesus of Nazareth was foretold in the Torah and the Prophets centuries before his appearance, and he was proved to be real and not a pretender due to his death and Resurrection. The early church grappled with all of this intellectually.

An enthusiastic admirer of the philosophy of Thomas Aquinas, professor and philosopher Peter Kreeft details the rational thought and precise literary talent that established Aquinas as the foremost thinker of his time - and as the most important philosopher for the almost 200 years between Aristotle and Descartes.

In his own day the dominant personality of the Western Church, Augustine of Hippo today stands as perhaps the greatest thinker of Christian antiquity, and his Confessions is one of the great works of Western literature. Now modern listeners will have easier access to St. Augustine's deeply personal meditations. Chadwick's lucid translation and helpful introduction clear the way for a new experience of this classic.

A seminal work of Spanish mysticism, Teresa of Avila's The Way of Perfection describes the practices and qualities of a prayerful life devoted to Christ. Although it was written over 500 years ago solely for the nuns of her convent, her devotion continues to instruct and inspire believers today.

L. Michael Morales examines the key elements of three major redemption movements in Scripture: the exodus out of Egypt, the second exodus foretold by the prophets, and the new exodus accomplished by Jesus Christ. We discover how the blood of a Passover lamb helps us grasp the significance of Jesus' death on the cross, how the Lord's defeat of Pharaoh foreshadowed Jesus' victory over Satan, how Israel's exodus out of Egypt unfolds the meaning of the resurrection, and much more.

First published in 1525, Martin Luther's Bondage of the Will is acknowledged by theologians as one of the great masterpieces of the Reformation. It is Luther response to Desiderius Erasmus' Diatribe on Free Will, written in his direct and unique style, combining deep spirituality with humor. Luther writes powerfully about man's depravity and God's sovereignty. The crucial issue for Luther concerned what ability free will has, and to what degree it is subject to God's sovereignty.

Saint Augustine's contributions to Christian theology are second to no other post-apostolic author in the whole sweep of church history. Yet along side his doctrinal treatises, Augustine tells a story of his life devoted to Christ as his only satisfaction. The Confessions is at once the autobiographical account of Augustine's life of Christian faith and at the same time a compelling theology of Christian spirituality for everyone.

As we all know, and as many of our well-established textbooks have argued for decades, the Inquisition was one of the most frightening and bloody chapters in Western history, Pope Pius XII was anti-Semitic and rightfully called "Hitler's Pope", the Dark Ages were a stunting of the progress of knowledge to be redeemed only by the secular spirit of the Enlightenment, and the religious Crusades were an early example of the rapacious Western thirst for riches and power. But what if these long-held beliefs were all wrong?

Reasonable, concise, witty, and wise, Peter Kreeft and Ronald K. Tacelli have written an informative and valuable guidebook for anyone looking for answers to questions of faith and reason. Topics include: faith and reason, the existence of God, God's nature, how we know God, creation and evolution, providence and free will, miracles, and more.

For many, the medieval world seems dark and foreign - a miraculous, brutal, and irrational time of superstition and strange relics. The pursuit of heretics, the Inquisition, the Crusades, and the domination of the "Holy Land" come to mind.

While many histories of Christian worship exist, this project undertakes a task both more focused and more urgent. Rather than survey the whole history of the Christian church, it focuses on the formative period between the first and fifth centuries CE, when so many of the understandings and patterns of Christian worship came to be. And rather than include such developments as the monastic hours of prayer and the history of ordination, the authors deal primarily with those aspects of worship that recur on a weekly or regular basis: preaching, Eucharist, and baptism.

"We are to love God for Himself, because of a twofold reason; nothing is more reasonable, nothing is more profitable." On Loving God is first a touching description of God's love for us as unmistakenly demonstrated in the death of His Son. Second, it is a call for us to joyfully respond to God like the child who runs and embraces her father whose love is sure. As St. Bernard writes, "They love all the more because they know themselves to be loved so exceedingly."

How would you describe your prayer life? Saint Paul urges Christians to: “Pray without ceasing.” (1 Thess 5:17) Do you pray without ceasing? Do you thank God for a new day when you rise? Do you ask God to protect you and guide you throughout your day? Do you seek God’s wisdom and courage as you encounter challenges, trials, and opportunities. Do you beg God’s forgiveness when you rebel against him? Do you long to spend more time in the presence of the Lord? Do you praise the “lover of your soul” with your every breath? If you want to do better in this area of your life, you are ...
